To all whom it concern: 7 Be it known that I, ALDEN PUTNAM, a citizen of the United States of America,

and State of Michigan, have invented certain new and useful Improvements in Metallic Vehicle-Wheels, of which the following is a specification, reference being had therein to the accompanying drawings. 7

The invention relates to vehicle wheels of the disk type and consists in-the novel construction as hereinafter set forth.

In the drawings Figure 1 is a centrallongitudinal section through the wheel; r Fig. 2 is a side elevation thereof. In the construction of vehicle wheels which are used as drivers it is usual to pro- -vide a brake drum which is secured to the.

hub or disk of the. wheel. With the present construction this brake drum is formed as an integral portion of the hub and together with a cooperating hubmember constitutes the attachment for the disk.

In detail, A is the rim or felly of the wheel; B is the disk which, as shown, is of dished form and of a cross-section which increases from the center toward the periphery. 'The central portion 0 of this disk extends in the plane of the wheel and is provided with a curved laterally projecting flange D. E is a hub member having a flange F which is parallel and lies adjacent to the portion C of the disk. G is a brake drum formed w'tha cylindrical outer ortion a radial inwardly projecting portion parallel tothe plane ofthe wheel, and a substantially cylindrical inner flanged portion I which constitutes a complementary portion of the hub. The ortion H lies ad acent to the portion of the disk and may be secured thereto by rivets J or other suitable means, the flange D constituting a pilot for accurately center ing the drum with the disk. This flange D also constitutes an abutment shoulder for taking the end thrust of the bearing3plaoed within the hub. The hub section is secured to the disk and member G either by rivets, as indicated at K, or by clampin bolts L. The section E may be provide with a radial outwardly-extending flange M for connection with the driver, and a ring N placed-w1thin said sectlon and bearing Specification of itettersratent.

with a portion of the "hub simplifies the construction and both of those portions may be formed simultaneously in the press. What I claim as my invention is:

I 1. In a vehicle wheel a pressed sheet metal member having an outer cylindrical flange, a radial inwardly-extending portion and an I inner concentric cylindrical flange constitut: 1 ing a portion of the hub, a cooperating hub secured to and extending oppositely from said radial inwardly extending portion, and a disk member secured between said hub section and the first mentioned member, said disk having an inner flange for fitting within the inner concentric cylindrical ortion and constituting a pilot for centering the hub with the disk.

2. In a vehicle wheel, a hub formed in two portions having parallel radial outwardly extending portions, adisk secured between said radlal outwardl extending portions and having a curvedfliange for fitting within one of said portions constitutin a pilot for centering'the hub with the dis and a brake flange formed integral with one of said radial outwardly extending portions.

3. In a vehicle wheel, a hub section and a brake drum formed from an integral pressed sheet metal member,-and a disk wheel member secured to said hub section and having a flange fitting within said hub section, constituting a pilot and centering said section with said disk member.

4. A vehicle wheel comprising a hubv formed in two sections, and -a brake drum integral with one section thereof, said sec tions being reversely formed with interior shoulders for opposite engagement by bearing members.

5. In a vehicle wheel, the combination with a pressed sheet metal member, comprising a hub section and an integral brake drum, ofa disk wheel member, secured to said hub' section, and means formed upon one of said members engaging the other member to relatively center the two members.

6. A vehicle wheel comprising a hub formed in two sections, a brake drum integral with one of said sections, said section, a disk wheel member clamped between said brake drum and flange,'and mem- 5 bers effecting the clamping engagement passthrough said flan e, disk and drum.

In a vehicle w eel, the combination with arim and-a two part hub, of a dished disk peripherally secured to said rim and clamped between the parts of said hub, in 10 close proximity to the plane of impact established by said rim.

In testimony whereof I affix m slgnature.
